Luteinizing Hormone (LH) is responsible for the final maturation of the ovarian follicle and the triggering of ovulation. Following ovulation, the same LH surge is also crucial for the transformation of the ruptured follicle into the corpus luteum. LH stimulates the remaining granulosa and theca cells of the follicle to undergo structural and functional changes, a process called luteinization. These cells become large, lipid-rich luteal cells and begin to secrete large amounts of progesterone and some estrogen, forming the active endocrine structure known as the corpus luteum. If pregnancy occurs, human chorionic gonadotropin (hCG) from the embryo takes over to maintain the corpus luteum. Without pregnancy, the corpus luteum regresses after about 10-14 days due to the withdrawal of LH support.
